[Fxruby-users] Proper way to display a right-click context menu

[Matthew M. <nam...@na...>]

Hi everyone,

I'm still learning and have a new question ;) I want my file manager application
to display a menu when an item in a FXList is right-clicked. The menu displays
fine, but once it is displayed my window manager freezes up and I have to go
to a console and kill my application, after which my X session is back to normal.

Here are the relevant parts from the initialize method in my FXWindow subclass. I
can post the whole thing if necessary.

    @rightClickMenu = FXMenuPane.new( self )
    FXMenuCommand.new( @rightClickMenu, "Cut\tCtl-X" ).
                  connect( SEL_COMMAND, method(:cmdCut))
    FXMenuCommand.new( @rightClickMenu, "Copy\tCtl-C" ).
                  connect( SEL_COMMAND, method(:cmdCopy))
    FXMenuCommand.new( @rightClickMenu, "Paste\tCtl-V" ).
                  connect( SEL_COMMAND, method(:cmdPaste))
    FXMenuCommand.new( @rightClickMenu, "Rename\tF2" ).
                  connect( SEL_COMMAND, method(:cmdRename))

    @list.connect( SEL_RIGHTBUTTONPRESS, method(:cmdRightButtonPress))

Other class methods:

  def cmdRightButtonPress( sender, sel, event )

    if @rightClickMenu.shown

      # @rightClickMenu.hide
      @rightClickMenu.popdown
    end

    @rightClickMenu.popup( getParent(),
			  event.win_x + self.getX, event.win_y + self.getY )
  end

  def onSelect( sender, sel, event )

    @selectedIndex = event
    if @ctrlPressed

      @selectedItems << @selectedIndex

    else

      @selectedItems.clear
    end

    if @rightClickMenu.shown

       @rightClickMenu.popdown
    end
  end

Currently the methods given to FXMenuCommand only call @rightClickMenu.popdown
and exit. I've looked at the C++ source for FXMenuTitle and it was some help; I
learned of the popup and popdown methods. The statements that are shown in that
file for using grap and ungrap methods doesn't work, undefined method errors are
returned.

Well, any insight or pointers to an example would be very helpful.

Take care, Matthew.
